Information inputting pen

Abstract

A stylus pen is obtained that allows accurate detection of a touched position regardless of the tilt of the stylus pen at a time of a touch operation on a capacitive touch panel. A stylus pen 100 comprises a pen body section 103 constituted of a non-conductive member and held by an operator, a pen tip section 102 formed, on one end of the pen body section 103 , to taper toward the tip side, and a spherical member 101 constituted of a conductive member and mounted on a tip of the pen tip section, where a contact member is mounted on the pen body section such that a hand of an operator contacts the contact member when the operator holds the pen body section, and the contact member and the spherical member are connected by a conducting wire penetrating through the pen body section and the pen tip section.
